IMN-Kolloquium: "Three-dimensional printing of transparent fused silica glass"

Am Mittwoch, 13.11.2019, um 13.00 Uhr spricht Dr. Dorothea Helmer, Albert-Ludwigs University of Freiburg, Laboratory of Process Technology | NeptunLab, im Rahmen des Kolloquiums des Instituts für Mikro- und Nanotechnologien MacroNano® der TU Ilmenau zum Thema "Three-dimensional printing of transparent fused silica glass". Die Veranstaltung findet im Feynmanbau, Gustav-Kirchhoff-Straße 7, Raum 114/115, statt.

Zum Vortrag: Fused silica glass is an important material due to their high chemical and thermal stability their outstanding optical transparency, hardness and well known surface properties. Due to these properties fused silica glass is an interesting material for future applications in chemical synthesis or optics and photonics. However, structuring of glasses is difficult, especially when high-resolutions are needed structuring is usually done using wet chemical or dry etching using hazardous chemicals.

We have previously described a new technology to fabricate and structure fused silica glass. We have therefore developed nanocomposites (called Glassomer) which can be processed like a polymer e.g. by UV casting, 3D printing or high-throughput polymer replication. After the structuring process the nanocomposites are turned into fused silica glass via thermal debinding and sintering. We have demonstrated that the sintered fused silica glass is chemically and physically identical to commercial fused silica glass. It shows the same high transparency in the UV, visible and infrared combined with the same mechanical strength, hardness and chemical and thermal resistance. Glassomer will enable many applications from optics and photonics and chemistry to life sciences and biotechnology.
